LangGraph settles into a maintenance window after the v3 streaming push

agent-runtimerelease-trainbugfixescli-toolingself-hosting
◆Current state
LangGraph's GitHub feed is a fast monorepo train spanning the core library, CLI, and Python SDK. This window is dominated by bugfixes and dependency bumps rather than new capability: checkpoint and subgraph regressions are being patched and the type checker is being migrated. The only net-new options are in the CLI.
◆Where it's heading
After the directional v3-streaming and RemoteGraph work in the 1.2.3 cycle, the project is hardening that surface: fixing snapshot/delta-channel roundtrips, subgraph checkpoint inheritance, and stream-abort cancellation. The CLI is picking up operational conveniences (HTTPS dev server, compatible API version ranges) that point at smoother self-hosted deployment.
◆Prediction
Expect continued point releases stabilizing v3 streaming and RemoteGraph, with the next feature signal more likely in the CLI/SDK deployment surface than in the core runtime.
